On July 2, 2026, the average sales-to-production ratio of polyester filament sample enterprises dropped to 31.7%, a decrease of 4.1 percentage points from the previous trading day. This figure indicates that nearly 70% of production failed to translate into actual sales, plunging market trading into a deep freeze. As cash flow remains high while downstream resistance intensifies, the chemical fiber supply chain stands at a delicate inflection point.
Behind the Data: Signals of Supply-Demand Imbalance
Examining the sales data from 25 sample enterprises on that day reveals an uneven distribution: the highest reached 70%, the lowest was 0%, with most concentrated between 15% and 35%. Specifically, two enterprises reported zero sales, and six had ratios below 20%, reflecting severe inventory buildup in some factories. Only three enterprises achieved ratios above 50%, accounting for 12% of the sample. This divergence suggests that the market is not uniformly weak but rather that selective procurement by downstream buyers is exacerbating structural imbalances.
Polyester filament cash flow remains high, implying relatively stable upstream raw material costs. However, downstream weaving mills are reluctant to purchase, as terminal demand from apparel and home textiles has not shown clear recovery. Weaving mills already face high inventory pressure, and buying expensive raw materials would further erode their already thin margins. This price tug-of-war between upstream and downstream essentially pits cost-push inflation against demand-suppressed deflation.
The High Cash Flow Trap: Short-Term Gains vs. Long-Term Risks
High cash flow appears beneficial for producers—strong profit margins per ton. But the persistently low sales-to-production ratio is undermining this advantage. At a 31.7% ratio, over two-thirds of daily output goes into inventory rather than the market. Assuming average inventory turnover days, if this trend continues for two weeks, sample enterprises' inventory could increase by roughly 40%, and carrying costs would quickly erode cash flow profits.
Historical precedents from 2019 and 2022 show that similar drops in the sales-to-production ratio were followed by price corrections. Currently, crude oil prices have lost upward momentum, and while Middle East tensions persist, they have not materially disrupted supply. Cost-side support is weakening. If upstream producers start to concede, downstream restocking may rebound quickly. But if the standoff continues too long, the risk of production cuts or price reductions will rise significantly.
Regional Impact: Ripple Effects Across Industrial Clusters
Major polyester filament production hubs such as Xiaoshan and Shaoxing in Zhejiang, and Shengze in Jiangsu, as well as downstream weaving clusters like Changle in Fujian and Shantou in Guangdong, are beginning to feel the pressure. A chemical fiber mill in Xiaoshan reported a decline in customer inquiries, with large orders nearly absent and only small batch purchases for immediate needs. In Shengze, weaving mill operating rates remain around 70%, but grey fabric inventory has climbed to over 45 days, making mills extremely cautious about raw material procurement.
This wait-and-see sentiment is spreading downstream. Apparel brands have slowed their 2026 autumn/winter order placements, and home textile exporters face intensified competition from Southeast Asia. Every link in the chain is trying to destock and reduce risk, resulting in persistently low upstream sales ratios. In the short term, this negative feedback loop is unlikely to break unless an unexpected demand stimulus or cost collapse occurs.
